my wife's 02 crv had the cel light on so she took it and had a scan of the codes, it showed code p0420-for the cat, and p085-( trans pressure switch b) i'm new to hondas so i'm not sure what the trans pressure switch b is and if the cat is failing could that cause the p085 code? trans fluid is at proper level and seems to shift fine when i drove it. any info would be greatly appreciated.
